Definitions

  • the present invention relates to a device comprising a first part made of a first material and at least a second part made of a second material, characterized in that the second part is made of a foam and assembled to the first part.
  • the technical field of the invention is the field of fine mechanics.
  • silicon has the drawback of having a very small plastic domain. Silicon is a fragile material that tends to break when subjected to too much stress.
  • a first method is to drive said gear on the axis as for a conventional gear wheel brass. But the hunting consists of a forced insertion of said axis in the hole of the cog. As silicon is a fragile material, the driving is very difficult because a high stress is applied to the silicon part and this generally causes the parts to break.
  • Another method is to use soldering / welding to attach the silicon part to its support.
  • this technique is also problematic because to have a chance of welding a ceramic material or silicon, it is necessary to use reactive solders / solders using temperature cycles and a neutral atmosphere or a high vacuum. This results in very long assembly cycles and risks of rupture / cracking of the silicon.
  • the bonding can also be used but it causes risks of degassing of organic compounds harmful to the operation of the movement and may cause aging problems (exposure of ultraviolet glue for skeleton movements).
  • the invention aims to overcome the disadvantages of the prior art by proposing to provide a method of assembling at least two parts between them which allows the attachment of two parts in a simple and safe manner without limitation as to the nature parts fixed together.
  • the first piece and the second piece are each provided with a cavity in which the amorphous metal preform extends.
  • the cavity of the first part and the cavity of the second part have different shapes.
  • the cavity of the first part and the cavity of the second part have different variable sections.
  • the first part and the second part have structures.
  • the method comprises a preliminary step of manufacturing an at least partially amorphous metal alloy foam preform.
  • the expansion of the foam is controlled by the temperature, the higher the temperature and the greater the expansion.
  • the expansion of the foam depends on the density of gas in the foam, the greater the volume of trapped gas is large is the greater the expansion will be.
  • the expansion is carried out having the pressure in the foam greater than that of the atmosphere.
  • the invention also relates to a device comprising a first piece and a second piece, a third piece made of a third material is used as an intermediate piece for fixing the second piece with the first piece, characterized in that the third piece is made at least partially amorphous metal alloy foam.
  • the first piece or the second piece is provided with a cavity in which the amorphous metal foam forming the third piece extends.
  • the first part and the second part are each provided with a cavity in which the amorphous metal foam forming the third part extends.
  • the cavity of the first piece and the cavity of the second piece have different shapes.
  • the cavity of the first part and the cavity of the second part have different variable sections.
  • the first piece and the second piece have structures.
  • the first piece and the second piece are arranged between them to allow the presence of a gap in which the at least partially amorphous metal alloy mouse forming said third piece will be shaped.
  • the present invention relates to a device and its method of assembly, the device comprising a first part and at least a second part.
  • the device 100 comprises a first piece 101 and a second piece 102, this second piece being assembled to the first piece via a third piece 103 used as an intermediate piece.
  • the first piece 101 is made of a first material while the second piece 102 is made of a second material.
  • first part 101 and the second part 102 are dimensioned so that, when they are mounted relative to each other, a gap 104 appears. This gap 104 is then used for an intermediate part 103 to be inserted therein, the latter being used to act as a seal.
  • the device 100 may be for example a wheel fixed on an axis. It is then considered that the first part 101 is the axis 111 and the at least one second part 102 is the wheel 112.
  • This wheel 112 is in the form of a circular piece pierced with a central through hole 112a. This circular piece therefore comprises an outer edge 112b on which teeth can be arranged and an inner edge 112c located at the central hole 112a.
  • the first material and / or the second material may be conventionally used materials such as steel, brass, aluminum or titanium, but they may also be so-called fragile materials.
  • Fragile material is understood to mean a material that does not have any exploitable plastic deformation, for example quartz, ruby, sapphire, glass, silicon, graphite, carbon or a ceramic such as silicon nitride and silicon. silicon carbide or a cermet composite. It is then understood that a piece in such a material is very fragile.
  • the wheel 112 is then assembled on the axis 111 so as to form the device 100.
  • the third part or intermediate piece 103 acting as a seal is made of a third material, said third material being an at least partially amorphous material comprising at least one metallic element such as an at least partially amorphous metal alloy.
  • this amorphous metallic material is in the form of a foam.
  • This metal element may be a conventional metallic element of the iron, nickel, zirconium, titanium or aluminum type or a precious metal element such as gold, platinum, palladium, rhenium, ruthenium, rhodium, aluminum or aluminum. silver, iridium or osmium. It will be understood by at least partially amorphous material that the material is capable of solidifying at least partially in amorphous phase, that is to say that it is subjected to a rise in temperature above its melting temperature allowing it to locally losing any crystalline structure, said rise being followed by cooling to a temperature below its glass transition temperature allowing it to become at least partially amorphous. This material can then be a metal alloy.
  • Such a foam can be made using different techniques.
  • a first method is to bring an alloy and heat it until it reaches a liquid state. At this time, gas bubbles are injected into said alloy in the liquid state. This injection of gas bubbles occurs before a rapid cooling step. This rapid cooling step is performed to solidify said alloy while trapping the gas bubbles.
  • a second method for producing such a foam is to provide an alloy and heat it until it reaches a liquid state. At this time, chemical agents are injected into said alloy in the liquid state. These chemical agents are gas liberating agents so that the latter, under certain conditions, release gases. This release of gases occurs before a rapid cooling step. This rapid cooling step is performed to solidify said alloy while trapping the gas bubbles.
  • a variant of this second method consists in providing a material capable of becoming a foam in order to obtain a material which becomes an amorphous metal foam only at the moment of its shaping.
  • the chemical agents used are liberating agents that release gases under certain conditions of temperature and pressure.
  • the pressure during cooling the release of the gas is contained.
  • the increase in temperature allows the release of the gas and therefore the transformation of the foam material.
  • the preform can be manufactured by compacting a mixture of powders (already amorphous metal powder with a precursor powder) using, for example, pressing or hot extrusion between the glass transition temperature Tg and the crystallization temperature Tx.
  • the chemical agents are present from the start, eg if the metal alloy is present in powder form the agents can be mixed with this metal powder before heating the mixture.
  • a third method for producing an amorphous metal foam consists of successive layers of powder layers, each layer of powder being sintered locally by a laser or electron beam. This local sintering thus makes it possible, at each layer of powder, to create the pores which will make it possible to form the foam.
  • the method of manufacturing and assembling said device comprises a first step of providing itself with an amorphous metal foam preform 115.
  • This preform has a shape similar to that of the interstice. For example, in the case of a wheel 112 assembled on an axis 111, the gap will be annular and therefore the preform will also be annular. It is also provided with a mold 124 formed of two matrices 124a, 124b. These two dies are hollowed so as to form, when associated, the negative of the device 100 assembled.
  • the axis 111, the wheel 112 and the foam preform 115 of amorphous metal are placed in the negative formed by the two matrices 124a, 124b.
  • the preform 115 of amorphous metal foam is thus placed between the axis 111 and the wheel 112, that is to say in its final location.
  • the preform is not the definitive part, there is some floating of this preform as visible on the figure 4 .
  • a heating step is performed.
  • This heating step consists in heating the assembly to a temperature between the glass transition temperature Tg and the crystallization temperature Tx of the preform.
  • Tg glass transition temperature
  • Tx crystallization temperature
  • the amorphous metals have a viscosity which decreases sharply, the decrease of the viscosity being dependent on the temperature. Since the amorphous metal of the foam is in a so-called viscous state, the expansion of the gas causes an expansion of the foam preform, this preform starts to swell. As a result, the volume taken up by the preform increases.
  • the negative formed by the two matrices is sized to have the dimensions of the final device assembled so that, when the preform inflates, the axis 111 and the wheel 112 are locked in their final position, the preform filling the gap 114 between them as visible to the figure 5 and exerts an isostatic pressure on the axis 111 and the wheel 112.
  • the pressure in the negative is lower than the pressure of the gas inside the preform, otherwise there can be no expansion.
  • a sealed mold it may be cleverly provided to put the cavity formed by the two matrices under vacuum.
  • the enclosure in which the mold is located is evacuated.
  • the pressure of the gas in the pores of the material before it is heated is greater than the ambient pressure, that is to say the pressure in the mold, the heating step can be carried out under ambient pressure. It is just necessary to have a pressure difference between the gas in the pores and the ambient pressure.
  • these two matrices can be fastened to each other via fastening means such as screws or simply by exerting sufficient pressure on them.
  • a cooling step is operated. This cooling step is made to freeze the amorphous foamed metal preform and form the intermediate piece.
  • the shaft 111 and the wheel 112 assembled with the intermediate part 103 are out of the dies to form the device 100 according to the invention.
  • An advantage of this embodiment is that it makes it possible to have an intermediate part acting as a seal which makes it possible to mount fragile parts without exerting too much stress and without having stress concentrations, the stresses exerted on the two parts being homogeneous and isostatic.
  • the surface of the first piece 111 and / or the second piece 112 in contact with the intermediate piece 103 of amorphous metal foam has a structuring 106 in order to improve the roughness and thus the grip of the first piece and the second piece with the intermediate piece.
  • the device is not limited to a wheel fixed to an axis and can be for example an ice-glass mounted on a middle-bezel or two tubes mounted one inside the other or any device in which an intermediate piece can be used to fill a gap and fix two pieces together.
  • the first part may be a support provided with a housing in which the second part or parts are arranged as for example a mosaic, the binder being the amorphous metal foam which exerts pressure on the first and second parts.
  • the first part may be a support provided with a housing in which the second part or parts are arranged, these being precise stones, the amorphous metal foam being the binder used to fix said gems to support.
  • cavities 107 may be added to the structures 106 and arranged at the axis and / or the wheel so as to have a cavity 107 arranged on the axis 111 and a cavity 107 arranged on the wheel 112 are at least partially facing each other when the shaft 111 and the wheel 112 are assembled. These two cavities 107 facing one another then form a housing 108. In this housing 108, the third part called intermediate part 103 is arranged.
  • the method of manufacturing and assembling said device comprises a first step of providing an amorphous metal foam preform.
  • This preform has a shape matching or similar to that of the housing 108 formed by the two cavities 107.
  • a second step is to bring the first piece and the second piece and place the preform in the housing.
  • the axis 111 and the wheel 112 are then aligned and held in this position.
  • a pressing or fixing means are used.
  • a third step the heating step is performed, this step consists of an expansion of the foam preform, this preform starts to swell.
  • this step consists of an expansion of the foam preform, this preform starts to swell.
  • the volume taken up by the preform increases and causes the housing formed by the two cavities to be filled with said amorphous metal foam.
  • a cooling step is performed. This cooling step is made to freeze the amorphous metal foam preform and form the intermediate piece which secures the first and second parts.
  • the first piece 101 and the second piece 102 assembled with the intermediate piece are taken out of the dies to form the device according to the invention.
  • This variant advantageously makes it possible to have an intermediate piece 103 totally invisible as shown in FIG. figure 8 .
  • the cavity 107 of the first piece 111 and / or the second piece 112 has a shape allowing to improve the grip.
  • a shape consists of a cavity 107 whose opening is not constant, that is to say that the surface of said opening varies according to the depth.
  • the cavity 107 may have, in a non-limiting manner, a rectangular trapezoid shape (A) or be spherical (B) or a T shape (C).
  • the preform becomes a foam only in the third step.
  • the foam uses precursor chemicals which release gas under the effect of a temperature, it has previously been described that the alloy containing these precursor chemicals can be made before they release the gas to obtain a preform is not in the form of a foam.
  • the method is to provide the preform is not in the form of a foam and place it in the mold.
  • the whole is then heated to a temperature allowing the precursor chemicals to release gas. This temperature also allows the gas to expand in order to expand the material.
  • control of the expansion of the amorphous metal foam preform can be done in several ways.
  • a first solution consists in modifying the density of the gas bubbles during the manufacture of the foam.
  • One method of making amorphous metal foam is to inject gas bubbles into the molten metal and cool it to trap these bubbles.
  • the injection of gas bubbles can be controlled so that the injection of gas bubbles is more or less homogeneous and more or less dense. It will be understood that the higher the density of the gas bubbles, the greater the volume of gas enclosed in the foam. However, the larger the enclosed volume of gas and the greater the expansion will be due to the expansion of the gas during the heating step.
  • the density of the bubbles can be controlled by modifying the density of the precursor agents so as to vary the density of gas released.
  • a second solution is to control the expansion of the amorphous metal foam by changing the temperature of the heating step. Indeed, when a gas is subjected to a warming, the amount of movement of the particles that compose it increases. At constant volume, this results in an increase in pressure because the number of shocks between particles per unit area increases. If the pressure must remain constant, the volume of the gas must then increase, according to the ideal gas law. Therefore, by increasing or decreasing the heating temperature during the heating step, the volume of the gas enclosed in the amorphous metal foam is varied and its expansion is therefore modified.
  • the control of the expansion of the amorphous metal foam is done by controlling the atmosphere in the heating chamber of the second embodiment or in the mold cavity in the first embodiment.
  • This solution assumes that expansion is possible from the moment when the pressure of the gas enclosed in the amorphous metal foam is greater than that of the atmosphere outside the foam.
  • the outside atmosphere should be empty sufficient to maximize the expansion of the foam. Therefore, by adjusting the external pressure, the amplitude of the expansion of said foam is adjusted knowing that the higher the pressure of the outside atmosphere and less gas expansion will be important.
  • the cavities may be replaced or completed with protuberances as visible in FIG. figure 10 .
  • These protuberances are the negatives of the cavities and have the same function.
  • the amorphous metal foam is shaped so as to be able to wrap this or these protuberances and improve the connection between the first piece and the second piece.
